RECOMMENDATIONS FOR THE PREPARATION, TRANSPORTATION AND STORAGE OF SHRINKAGE COMPENSATED CONCRETE MADE OF RECYCLED LOW-MODULUS AGGREGATES

Abstract

The properties of concrete with cube compressive strength up to 66 MPa made of re-used
aggregates were studied in comparison with ND concrete. Both re-used aggregates obtained
from ND and LWA concrete in different proportions were used. Sulfo-aluma expansive admixture
was used to compensate high shrinkage of concrete made of re-used aggregates. The
relationships between compressive strength and E-modulus, strain at the peak stress, indirect
tensile strength and others are discussed and recommended for practical use. Regulations estimates
of destination are proposed.
